Surface Area Mastery
An interactive lesson on screen. Your child works through worked examples, practises on their own, then tests themselves with questions that get harder as they go.
About this lesson
By the end of this lesson your child can find the surface area of any cuboid or cube, whether they are counting squares, reading a net, or working backwards from a surface area they have been given, and know instantly which method it needs.
Topics covered:
- Area revision, rectangles, triangles and compound shapes
- Counting the squares on each face of a solid cuboid
- Reading the surface area off a net
- Surface area of a cuboid using the three pairs of faces
- Surface area of a cube
- Finding the side length of a cube from its surface area
- Finding a missing dimension when the surface area is given, a stretch unit for the most competitive grammar schools
- Word problems, paint, wrapping paper and cost per square metre
Your child works through this lesson on any screen. They click to reveal each step of a worked example, try the practice questions on paper, then click to check their own answer.
How it's structured:
- Each unit opens with two worked examples your child clicks through line by line, then practice questions colour-coded easy, medium and hard
- 88 practice questions in total, each with a click-to-reveal answer and a reveal-all option
- A final 12-question mixed challenge pulling from all 8 units, including a cube cut out of a corner, an open box with no lid, and two cuboids glued together
Two interactive tools sit at the front of the lesson. On the first, your child clicks a face of a cuboid and the squares covering it get counted in front of them. On the second, that same cuboid unfolds into a net, and clicking one face flashes its matching partner, so the three pairs stop being a formula to memorise and start being something they can see.
Use this if:
- Your child is in Year 4 to Year 11 and needs to get confident with 3D shape questions
- You're preparing for the 11+, where surface area and nets turn up in the non-calculator paper
- Your child is doing GCSE Foundation and loses marks by forgetting the back three faces
- You want a resource your child can check their own work with, not one more thing on your to-do list

FAQs
How do I access the lesson?
You'll get an email with your lesson link as soon as payment goes through. Click it to open the lesson in any browser, no login and no app to install.
How does the marking work?
There's no typing answers into a box. Your child works it out on paper, then clicks to reveal the correct answer and checks their own work. Full working is shown too, not just the final answer, so mistakes are easy to spot.
Does it work on a phone or tablet?
It works best on a tablet or laptop, where there's more room to read the examples and questions. It'll open on a phone too, but the text and diagrams can feel quite small on a smaller screen.
Can I use the lesson more than once?
Yes. There's no limit on how many times you open the link, so it's there for revision right up to the exam.
